Similar applies to the T-34/85. It is way cheaper and can win when Panther and T-34/85 are both facing their sides/rear at each other.
And a King Tiger loses to a single guard with a PTRS if it's on Prioritize vehicle.
The Panther is faster than a T34/85. It has double the front armor of a T34/85. It has 10 more range than T34/85. It has higher penetration than a T34/85. If you lose a Panther to a T34/85, you have only yourself to blame.
